llm-generate · MCP LLM Generator v2 MCP: Risk & Policy

WHAT IT DOES

What llm-generate does on MCP LLM Generator v2

AI agents invoke llm-generate to trigger actions in MCP LLM Generator v2. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why llm-generate needs a policy

This tool triggers an external LLM generation operation via a delegation protocol. It executes a text generation request through an external system (client-to-LLM), making it an Execute category tool. The effects depend on the arguments passed (prompt, context, etc.).

Verdict

llm-generate Rate-limited

llm-generate stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about llm-generate

What does the llm-generate tool do? +

Generate text using LLM via MCP sampling protocol (server-to-client-to-LLM delegation). It is categorised as a Execute tool in the MCP LLM Generator v2 MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on llm-generate? +

Register the MCP LLM Generator v2 MCP server in PolicyLayer and add a rule for llm-generate: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP LLM Generator v2. Nothing to install.

What risk level is llm-generate? +

llm-generate is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit llm-generate? +

Yes. Add a rate_limit block to the llm-generate rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block llm-generate completely? +

Set action: deny in the PolicyLayer policy for llm-generate. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides llm-generate? +

llm-generate is provided by the MCP LLM Generator v2 MCP server (mako10k/mcp-llm-generator). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
